my gtr is only around 1200whp and destroys stage 4 991s, all bikes, all local 997s etc (so far). I dont think i will stand a change against adams car, but i will be at shift-sector in may with it expecting an *** kicking. If he is whopping 1600whp GTRs like this then i am gonna give up before we even begin.

haha glad I could give you some more GTR material brother!
If you have never been to Coalinga, just be prepared to launch like it's on ice. No joke I sometimes prepare for it by practicing launching when it's wet outside (not flat out rain but drizzling). I would love the opportunity to run you but I can't make the May event. Good luck out there and be safe.
It's a GPS-based data acquisition tool. I got it to evaluate my track driving but it is used by the car magazines and even auto manufacturers to do development and acceleration testing. You just plug it in to your car's cigarette lighter and put in an SD card. The vbox records all the information of the car's movement. The website www.vboxverify.com will take the raw data saved as a .dbn file and convert it to those graphs you see that I posted. It's the only legit source for posting acceleration data.
haha thx. Would be insane for me to sell this car at the current market price. Nothing in that price range could do what this car does.

Porsche makes these PDK's amazing and bullet proof for stockish power. They also seam to handle pretty well up to 650-700 TQ, but give issues after that power level.
From my understanding Adam only broke an axel when he went with a sticker tire and then switched back and never had an issue since.
BBI has recently modded a PDK as well. They're just starting to crack those open.

I think it takes a bit more than 100 extra HP to mess up the clutches and tranny. I would think a tune and proper exhaust would add around 100 HP and that's a very basic setup many cars are running without issues. OP's car has way more mods and gets launched habitually.
See below.

Yes, DRs at a prepped drag strip...never again! Glad the axle snapped because by doing that it protected the PDK.
Yeah so you and PDX bring up a good point. How much can the PDK handle?
My car is a good one to make the determination because I am at elevated power levels and I take my car to the limit.
So the question is, how much power am I making?? Dyno variations are significant and that topic has been beat to death. I could make 530 on GMG's 600 on GIAC's and then 720 on Cobb's. Seriously. There is massive dyno deviation around here.
The best tool to measure my engine power is on a manufacturer's dyno. Ain't gonna happen. But the next best thing is probably the horsepower calculator on www.vboxverify.com It calculates how much power the car is actually putting to the ground based on vBox results, weather conditions, and details of the car, rolling resistance, aero, etc. If you guys haven't tried it, it's pretty amazing.
So inputting my vBox records from airstrip events says I'm making between 650 and 690 wheel HP. When I got out on a cold morning the figure reach in the 720's...to the wheels. It does not tell the torque figure but I would say it's just as high. We can argue this tool as well but given that there are auto manufacturers and race builders using this site, it's pretty legit.
I have absolutely no issue with my PDK, except it slips at WOT unless I'm in Sport or Sport Plus. Those mods simply increase line pressure. But in those mods the trans shifts perfectly.
Figuring driveline losses, it is likely in my estimation that my car is really making upwards of 750 crank TQ. And given that it has been launched so many times, it's likely that the PDK is more robust than people imagine. The weak link is that the clutches slip with too much torque. So when a car has say 800-900 TQ, it doesn't necessarily mean the PDK needs to be built, it might just need more line pressure to prevent it from slipping.

on a generalized calculator off trap speed in 1/4 mile your car makes 580-600 . they usually arent far off either way , but general.
side note, which vbox do you use? the sport ?
